Now the summer is over, most of us are seeking the sartorial segue to autumn. Your footwear decisions are fundamental to transitional style, and to keep on trend the only choice is the statement heeled ankle boot. But while ankle boots work effortlessly with jeans, giving a touch of Parisian chic, it's easy to become unstuck when attempting to work them with a skirt. The key to success, as so often in life, is ensuring that your skirt is short enough. So that's a no to anything near knee length, unless you like your legs looking truncated. With short hemlines comes the risk of the slut factor. Avoid it like Alexa Chung did by going for an edgier look. While her red dress may be a mini, she covers her arms and décolletage, landing the perfect style/slut compromise. And when choosing your boots? Hazards include styles cut too high so that they foreshorten the leg and heels that aren't high enough. If you can't face bare legs, go for sheer patterned tights and nail two AW trends in one.
